PROBLEM TO BE SOLVED: To provide a game machine reducing defects related to a sensor. SOLUTION: The game machine includes a game board having a game area where a ball rolls, a shooting handle to shoot a ball to the play board, a ball storing tank 510 to store balls, a ball path case and a upper plate to supply a ball stored in the ball storing tank 510 to the shooting handle and a stored ball sensor 511 to detect whether balls are stored in the ball stored tank 510 or not. The stored ball sensor 511 comprises a slider 513 which works with the presence/absence of balls and a distance measuring sensor 512 to detect the position of a projection 513a of the slider 513.
